Monitoring has always been the engineers’ best friend as it turns apparent chaos into order and helps us understand what is going on deep inside a system to deliver high-quality pictures and sound. As OTT continues to play a more prominent role, the need to monitor internet distribution systems is becoming increasingly compelling.
With mature, cloud-based services now prevalent across the industry, helping to process and distribute content faster and more accurately than ever before, the long sought-after promise of producing content in the cloud—reducing cost and physical barriers—prompted broadcasters and production companies to experiment with new ways to make it a common reality.
IP is empowering broadcasters the world over to improve flexibility, scalability and resilience. We often describe the internet in “fluffy cloud” terms, but to truly leverage its capabilities, broadcasters must now dig into the detail of its operation.
What is the internet? Who is the internet? Where is the internet? These are the first three questions on the tip of every engineers and technologist’s lips. Before we can ever possibly hope to work with internet technology, we must be able to answer these three basic questions.
In the beginning, there was television. And whenever people tried to make television programmes effective video signal monitoring was an essential pre-requisite.
Synchronizing became extremely important with the growth of AC power systems, which ended up being used to synchronize all sorts of equipment, from Radar to television.
The power and flexibility of cloud computing is being felt by broadcasters throughout the world. Scaling delivers incredible resource and the levels of resilience available from international public cloud vendors is truly eye watering. It’s difficult to see how any broadcaster would run out of computing power or storage, even with 4K and 8K infrastructures.
In this second instalment of our extended article looking into the practical applications of SDI and IP we look at how SDI is naturally plug-and-play and works with well-defined formats whereas IP is dynamic and more versatile but requires greater thought in making it work reliably.
